FIELD OF THE INVENTION

The present disclosure generally relates to the field of light emittingdiode (LED) lighting technology and, more particularly, relates to anLED lighting device, a wireless speaker system and a wireless audioplaying method.

BACKGROUND

Digital Living Network Alliance (DLNA) is a collaborative tradeorganization established by Sony, Intel, Microsoft, etc. DLNA isresponsible for defining interoperability guidelines to enable unlimitedsharing of digital media and content services between multimediadevices, such as personal computers (PCs), consumer electronics andmobile devices. Airplay is a playing technology added in iOS 4.2 and OSX Mountain Lion by Apple Company. By using the Airplay technology, videomirroring on iPhone, iPod touch, iPad and Mac can be transmitted todevices (e.g., speaker, Apple TV, AirPort Express) that support Airplay.

LED lighting may generally provide advantages in energy conservation,environmental protection, controllable lighting, solid state lighting,and long operational lifetime. LED lamps thus have been widely used invarious areas for public, commercial, and/or indoor lightings.

A wireless speaker system can be combined with a LED lighting device.Through DLNA or Airplay technology, a smart terminal can share an audiosignal with the LED lighting device that supports the DLNA or Airplaytechnology. However, in an existing system of the wireless speaker withthe LED lighting device, when playing the audio signal, a specificwireless transmitting telephone needs to be added to control and sendthe audio signal. The size of such a wireless transmitting telephone islarge and the cost is expensive, which is not a good match for growingsmart terminals, such as smart mobile phones. In addition, thecompatibility for such a wireless transmitting telephone is poor. It isusually unable to adapt to the needs of more occasions. Further, theexisting wireless speaker system may only include a single LED lightingdevice and can only play in mono. Therefore, a stereo wireless speakersystem may be desirable to meet user needs.

The disclosed LED lighting devices, wireless speaker systems, andwireless audio playing methods are directed to solve one or moreproblems set forth above and other problems.
